Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461386, here are decompositions:

37 + 31461349 = 31461386
43 + 31461343 = 31461386
157 + 31461229 = 31461386
163 + 31461223 = 31461386
193 + 31461193 = 31461386
223 + 31461163 = 31461386
337 + 31461049 = 31461386
349 + 31461037 = 31461386

Showing the first eight; more decompositions exist.
